Words • 1196
Pages • 5
Plate tectonic theory is important in explaining the reason the world today is made of many land fragments and is not a single piece. It expounds on how the outer shell of the earth is made of plates that move over the mantle. Stern, further elaborates plate tectonics as the movement of the thermal earth boundary horizontally over asthenosphere and is fastened by the lithosphere sinking in several subduction zones. This movement is responsible for the formation of some new…...

First proposed by Alfred Wegener the meteorologist, the theory of continental drift supports the belief that the Earth’s continents once were a single land mass. This land mass, which was named “Pangaea”, broke up, and its various parts drifted away from one another. Centuries ago, trips around the world from travellers showed out lines from every continent around the world. Later on, early mapmakers wondered why these continents fit together so well. Early geologist thought at first that the continents had…...

Types of Rocks Geologists classify rocks in three groups, according to the major Earth processes that formed them. The three rock groups are igneous, sedimentary, and metamorphic rocks. Anyone who wishes to collect rocks should become familiar with the characteristics of these three rock groups. Knowing how a geologist classifies rocks is important if you want to transform a random group of rock specimens into a true collection. Igneous rocks are formed from melted rock that has cooled and solidified.…...

фAs it spreads away from the ridge and cools and contracts, or becomes denser, it is able to sink into the hotter underlying mantle. When two oceanic plates collide, the younger of the two plates, because it is less dense will ride over the edge of the older plate. The density of the rock that makes up the subjecting plate determines the way in which a plate behaves. A plate with a greater density subjects into the mantle faster and…...
